Improves jpeg auto-detection.

This option is typically useful when cross-compiling dynamic libraries
for iOS, with something such as --install-name-dir=@rpath

optimize draw_bar_yuv (slightly faster)
optimize draw_axis (about 2x faster)

This commit redistributes the leftover bytes amongst the top 150 slices
in terms of size (in the hopes that they'll be the ones pretty bitrate
starved).

A more perceptual method would probably need to cut bits off from slices
which don't need much, but that'll be implemented later.

Previously a global average was used. Using the previous quantizer
resulted in a fairly significant speedup as slice size selection settled
down quicker.

16 bits were definitely not enough and caused artifacts to appear on
images at barely compressed images.

Needed for following commits, also a speed increase.
